I spend a lot of my time sitting in front of terminals if you have not yet guessed. When dealing with different user accounts across different systems and a plethora of terminals open its nice to have a bit of information about who you are, and where you are. I also like to be able to easily differentiate output from different commands. If your interested read on.
You will want to edit your user .bashrc as well as your /root/.bashrc. For your user append this line
PS1="\n[\u@\h] \w\n$ "
This will give you output like this on your terminal.
[cmdln@neuron] ~/test $ ls file file2 [cmdln@neuron] ~/test $
And for /root/.bashrc you will want to append
PS1="\n[\[033[1;31m\]\u\033[0m\]@\033[1;33m\]\h] \w\n$ "
This will give you output like this.
[root@neuron] /home/cmdln/test # ls file file2 [root@neuron] /home/cmdln/test #
